Crantz Rosen

Crantz Rosen (クランツ・ローゼン Kurantsu・Rōzen) is Licht Jekylland Todoroki's manager and also somehow his "babysitter". He is originally from France but is also able to speak English, Japanese and German.

Appearance
Crantz is a young man with green eyes and long beige hair that he braided to the left side. He usually wears purple suit with white shirt underneath and red necktie.

While assisting Misono and the others to rescue Lawless and Licht, Crantz tied his hair into ponytail while still keep a small braid on his left side. He wears turquoise shirt with flowery pattern and white t-shirt underneath it and a yellow pants.

Personality
Crantz is a gentleman who is dedicated on his work as Licht's manager and even considers himself as his "babysitter". After Lawless joins them, Crantz usually works together with Guilderstern on making sure that the Greed Pair behave themselves and gives them a scolding if they are misbehaving. In Lawless' case, whenever the servamp refuse to listen, he will use holy water to silence him, prompting the servamp to comment that Crantz is scary. He is greatly fascinated of Licht's piano play and determines to spread it throughout the world, going as far as describing it as a treasure of humanity. He also becomes the voice of reason for Licht, having more understanding on the situation than he has.

Ambush in Tokyo Concert
He first appears when Licht is in Tokyo to hold a concert. He accompanies Licht not only as his manager but also to take care of him and look after him.

He knows about vampires, although he is neither a subclass nor an Eve. Lichts mascots is Lawless' only known subclass and mostly seen in a whale costume and accompanying Crantz.

In the concert hall he sees Mahiru Shirota who sneaks around without having tickets, however, he says he will give Mahiru the opportunity to listen to Licht's piano play as he thinks more kids his age should appreciate classical music. Before he can give Mahiru the tickets however he takes off after realising Tsubaki has set a trap for Licht and Lawless.

Later he sees Licht and Lawless fighting again, so he sends Güldenstern to stop the two of them. After the fight ends (stopped by Güldenstern) Crantz explains to Licht, why he shouldn't fight with Lawless - Licht schould be more mature. If Licht got hurt by Lawless or hurts himself, that would be bad - worst case: he wouldn't be able to play the piano again.

Mahiru explains to Crantz, that all of the audience are Tsubakis Subclass - Crantz mentions, that he'd never heard of Tsubaki, but is willing to make Licht and Lawless help Mahiru and Co. to fight that vampire (because Tsubakis seems to be after Licht too).

Rescuing Lawless and Licht
About 6 a.m. (the day after the concert) Rosen Crantz recieves a call from Licht - Licht asks where shit rat (Lawless) could be (something he's never done before). When Licht tells Crantz, that his body feels all heavy and weak, he suddenly realizes that Lawless must have seperated too far from Licht.

Crantz has no idea where Lawless could be, so he phones Mahiru to help him.
